UFO sightings were all the craze in the late 1940s and into the 1950’s. I was just a kid but remember the “ Operation Blue Book” on UFO sightings from 1947 thru 1969. It investigated over 12,000 sightings (reported) and claimed to be able to explain all but a bit over 700 of them.
(in the late 1940s and into the 1950’s) ....I can remember back in the mid, or maybe late 40’s, we boys were playing outside, and for the first time ever, saw an aircraft leaving a contrail. We thought the heavens were opening up. Scared the hell out of us kids.
